Description

Technical Field

[0001] This application relates to the technical field of kitchen utensils, and particularly to a pressure cooker lid and a pressure cooker. Background Art

[0002] A pressure cooker is a common cooking appliance, and its main function is to increase the heating temperature by increasing the air pressure inside the pot, thereby improving the heating speed. A pressure cooker mainly consists of a pressure cooker lid and a pot body. A connection is formed between the pressure cooker lid and the pot body through a clamp. The clamp can move relative to the pot body to simultaneously clamp or release the pressure cooker lid and the pot body. However, the existing clamp device is relatively laborious to operate. Summary of the Invention

[0003] This application provides a pressure cooker lid and a pressure cooker to solve the technical problem that the clamp assembly in the above-mentioned prior art is relatively laborious to operate.

[0004] In a first aspect of this application, a pressure cooker lid is provided. The pressure cooker lid includes a lid body and a clamp device that are detachably connected. The clamp device includes:

[0005] A support member for connecting the lid body;

[0006] At least two clamps that are slidably connected to the support member and can slide radially along the lid body. The clamp is provided with a guide groove that extends linearly from the center of the clamp to one side, and the extending direction of the guide groove is perpendicular to the sliding direction of the clamp;

[0007] A rotating member that is rotatably connected to the support member. The rotating member is provided with a guide post that cooperates with the guide groove to convert the rotation of the rotating member into the radial movement of the clamp.

[0008] The pressure cooker lid provided by the present application includes a lid body and a clamp device that are detachably connected. The clamp device includes a support member, at least two clamps, and a rotating member; the support member is used to connect the lid body. That is to say, the support member forms the main part of the clamp device, and other components of the clamp device are all installed on the support member, so that the clamp device can be used as a whole and be detachably connected to the lid body, thus facilitating disassembly, assembly, cleaning, and maintenance; the clamps are slidably connected to the support member and can slide radially along the lid body to achieve clamping and releasing clamping. The clamps are provided with guide grooves; the rotating member is rotatably connected to the support member. The rotating member is provided with guide posts, and the guide posts cooperate with the guide grooves to convert the rotation of the rotating member into the radial movement of the clamps, so that the clamps can achieve clamping or releasing clamping; the guide grooves extend linearly from the center of the clamps to one side, and the extending direction of the guide grooves is perpendicular to the sliding direction of the clamps. This can not only simplify the structure of the guide grooves, simplify the production process, and reduce the production cost, but also can increase the actual rotation angle of the rotating member as much as possible to achieve labor-saving operation.

[0009] Optionally, the rotating member has a first rotation stroke and a second rotation stroke; along the direction away from the clamps, the guide groove includes a first end point, a separation point, and a second end point; within the first rotation stroke, the guide post is located between the second end point and the separation point, and the clamps can achieve clamping or releasing clamping. That is to say, in the section where the clamps are close to the axis of the lid body, it can prevent the clamps from being damaged by external forces and ensure the safe use of the clamps; within the second rotation stroke, the guide post is located between the first end point and the separation point, and the clamp device can achieve installation and disassembly. That is to say, in the section where the clamps are far from the axis of the lid body, it can avoid interference or collision between the clamps and the edge of the lid body during the disassembly process and ensure the smooth installation and disassembly of the clamps.

[0010] Optionally, the lid body is provided with a detachable check valve. The check valve passes through the lid body and can rise or fall along the lid body; the clamp is provided with a first avoidance groove, and the check valve passes through the first avoidance groove and can slide along the first avoidance groove; when the guide post moves to the separation point, the check valve abuts against the groove wall of the first avoidance groove. Under normal use conditions, the check valve limits the farthest position of the clamps. After the clamps slide to the position of releasing clamping, they cannot further slide in the direction away from the axis of the lid body, so as to ensure that the clamp device will not accidentally fall off during the use state; when it is necessary to disassemble the clamp device, it is necessary to first remove the check valve. After the clamps slide to the position of releasing clamping, they can further slide in the direction away from the axis of the lid body, so as to achieve the smooth disassembly of the clamp device.

[0011] Optionally, the first avoidance groove includes a first groove section and a second groove section that communicate with each other. The first groove section is farther from the axis of the lid body than the second groove section, and the groove width of the first groove section is greater than that of the second groove section. When the anti-opening valve is in the raised position, the anti-opening valve passes through the first groove section, and the anti-opening valve is blocked by the first groove section and cannot slide into the second groove section, ensuring reliable retention in the clamping position under high pressure and preventing the lid of the pot from accidentally opening under high pressure. When the anti-opening valve is in the lowered position, the anti-opening valve can slide into the second groove section along the first groove section, so that the clamp can freely switch between the clamping position and the unclamping position.

[0012] Optionally, a first valve sleeve is provided through the lid body. The first valve sleeve is in sealing cooperation with the lid body, and the first valve sleeve presses the lid body from bottom to top. A second valve sleeve is provided through the support member. The second valve sleeve presses the support member from top to bottom. The first valve sleeve is threadedly connected to the second valve sleeve, and an installation hole is formed between the first valve sleeve and the second valve sleeve. The pressure cooker lid further includes an anti-opening valve that passes through the installation hole and can slide along the axis of the installation hole. Adding the mutually cooperating first valve sleeve and second valve sleeve at the installation position of the anti-opening valve serves as a threaded fastener to realize the connection between the support member and the lid body, reducing the number of fasteners, lowering the production cost, and eliminating the need to provide dedicated connection holes in the lid body or the support member, enabling the pressure cooker lid to maintain a high degree of integrity.

[0013] Optionally, the pressure cooker lid further includes a first screw. The first screw and the anti-opening valve are spaced apart along the movement direction of the clamp, and the first screw and the anti-opening valve are respectively located on both sides of the axis of the lid body. The first screw passes through the lid body and is connected to the support member. The first screw and the valve body together achieve the installation and fixation of the support member. There is a large connection span between the first screw and the valve body, thereby increasing the reliability of the connection and preventing the support member from shaking or rotating, resulting in loosening or falling off of the support member.

[0014] Optionally, the support member is provided with an elastic locking member, and the rotating member is provided with a locking groove. The elastic locking member is engaged with or disengaged from the locking groove to lock or unlock the rotating member, so that the clamp can stably stay in the expected position and prevent the clamp from moving freely, resulting in the clamp being unable to achieve the expected function.

[0015] Optionally, the rotating member includes a turntable and a handle that are connected to each other; the turntable is arranged below the support member, the guide column is protruding from the surface of the turntable, and the handle is arranged above the support member; thereby, the structure for realizing transmission is arranged on the side of the support member facing the cover body to prevent accidents such as pinching the user, and the appearance of the pressure cooker cover can be improved. The structure for realizing gripping is arranged on the side of the support member away from the cover body to make operation more convenient.

[0016] Optionally, the rotating member also includes a support sleeve and a fastening assembly, the support sleeve is inserted through the turntable and the handle, and the fastening assembly is inserted through the support sleeve; the fastening assembly axially presses both ends of the support sleeve, and the fastening assembly axially presses the turntable and the handle; the axial force exerted on the turntable and the handle is limited by the support sleeve to prevent the turntable and the handle from being damaged due to excessive force, and since the support sleeve is not easy to deform, the axial force of the fastening assembly will not change significantly, thereby preventing the fastening assembly from loosening during use.

[0017] Optionally, a first connecting column is provided upwardly protruding from the center of the turntable, and a first connecting hole is provided at the center of the handle, and the first connecting column is plugged into and fit with the first connecting hole; in the area where the first connecting column and the first connecting hole fit together, the cross-section of the first connecting column and the cross-section of the first connecting hole are arranged to form a non-circular structure, thereby preventing the handle and the turntable from rotating relative to each other and ensuring that the turntable rotates together with the handle.

[0018] Optionally, a second connecting column is protruding below the handle, and the second connecting column is offset from the center of the handle; the turntable is provided with a second connecting hole, and the second connecting hole is offset from the center of the turntable. The second connecting column is plugged into the second connecting hole, which can prevent the handle and the turntable from rotating relative to each other and provide a larger torque, thereby making the turntable easier to rotate.

[0019] Optionally, a plurality of fins are protruding from the outer side of the second connecting column, and the fins extend downward from the handle. The lower ends of the fins are against the turntable, and the fins are distributed at circumferential intervals around the second connecting column to increase the supporting strength of the second connecting column and prevent the second connecting column from being damaged such as bending.

[0020] A second aspect of the present application provides a pressure cooker, comprising a cooker body and any one of the pressure cooker covers provided in the present application, wherein when the pressure cooker cover is connected to the cooker body, the clamping device can clamp the pressure cooker cover and the cooker body simultaneously.

[0070] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments consistent with this application, and are used together with the specification to explain the principles of this application. Detailed implementation manners

[0071] In order to make the objectives, technical solutions and advantages of this application more clear and understandable, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0072] In the description of this application, unless otherwise clearly specified and defined, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; unless otherwise specified or stated, the term "plural" means two or more; the terms "connection", "fixation", etc. should all be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0073] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of this application are described from the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0074] As Figure 1 shown, the embodiments of this application provide a pressure cooker, which includes a pressure cooker lid 01 and a pot body 02, and the pressure cooker lid 01 is detachably connected to the pot body 02. Among them, the pressure cooker lid 01 includes a detachable lid body 1 and a clamp device 2. For example, the clamp device 2 can be connected to the lid body 1 by means of screws or buckles. When the pressure cooker lid 01 is connected to the pot body 02, the clamp device 2 can simultaneously clamp the pressure cooker lid 01 and the pot body 02, so as to realize the reliable connection between the pressure cooker lid 01 and the pot body 02; the lid body 1 is provided with a sealing ring 13, a pressure limiting valve 12 and a safety valve 11; the sealing ring 13 can form a sealed state between the pressure cooker lid 01 and the pot body 02 to prevent the gas in the pot from leaking between the pressure cooker lid 01 and the pot body 02; the pressure limiting valve 12 is used to limit the maximum pressure in the pot; the safety valve 11 passes through the pressure cooker lid 01 and can rise or fall along the pressure cooker lid 01. When the safety valve 11 rises, a sealed state is formed and high pressure can be formed in the pot; when the safety valve 11 falls, a pressure relief state is formed and the pressure in the pot is released.

[0075] As Figures 1-9As shown in the figure, the clamp device 2 includes a support member 21, at least two clamps 22, and a rotating member 23. The support member 21 is used to connect to the cover body 1. That is to say, the support member 21 forms the main body part of the clamp device 2, and other components of the clamp device 2 are all installed on the support member 21, so that the clamp device 2 can be regarded as a whole and is detachably connected to the cover body 1, thus facilitating disassembly, assembly, cleaning, and maintenance; the clamp 22 is slidably connected to the support member 21 and can slide radially along the cover body 1 to achieve clamping and releasing of clamping. The clamp 22 is provided with a guide groove 221; the rotating member 23 is rotatably connected to the support member 21, and the rotating member 23 is provided with a guide post 231. The guide post 231 cooperates with the guide groove 221 to convert the rotation of the rotating member 23 into the radial movement of the clamp 22, so that the clamp 22 can achieve clamping or releasing of clamping; the guide groove 221 extends linearly from the center of the clamp 22 to one side, and the extending direction of the guide groove 221 is perpendicular to the sliding direction of the clamp 22, which can not only simplify the structure of the guide groove 221, simplify the production process, and reduce the production cost, but also can increase the actual rotation angle of the rotating member 23 as much as possible to achieve labor-saving operation.

[0076] As Figures 2-5 shown, specifically, the support member 21 is centered on the axis of the cover body 1. The edge of the support member 21 is provided with a cavity extending radially along the cover body 1. A part of the clamp 22 is accommodated in the cavity and can slide along the cavity; for the convenience of installing the clamp 22, the support member 21 can be set as a first part 21a and a second part 21b that are spliced together. The above-mentioned cavity is formed between the first part 21a and the second part 21b, and the first part 21a and the second part 21b can be connected into a whole by means of screws or the like.

[0077] Among them, the rotating member 23 is rotatably connected to the center of the support member 21, and the clamps 22 are distributed at intervals around the center of the support member 21; the guide posts 231 correspond to the clamps 22 one by one. That is to say, one guide post 231 is provided on the rotating member 23 corresponding to each clamp 22, and the guide posts 231 are distributed at intervals around the center of the support member 21.

[0078] Furthermore, the support member 21 is provided with an elastic locking member 211, and the rotating member 23 is provided with a locking groove. The elastic locking member 211 is snapped into or out of the locking groove to lock or release the rotating member 23, so that the clamp 22 can stay stably in the expected position. For example, the clamp 22 can stay stably in the clamping position, the releasing position, or the disassembly position, etc., to prevent the clamp 22 from moving freely, resulting in the inability of the clamp 22 to achieve the expected function.

[0079] Further, the rotating member 23 includes a turntable 23a and a handle 23b that are connected to each other. The turntable 23a is disposed below the support member 21, and the guide post 231 protrudes from the surface of the turntable 23a. That is to say, the structure for realizing transmission is disposed on the side of the support member 21 facing the cover body 1, preventing accidental situations such as pinching the user, and also improving the appearance of the pressure cooker lid 01; the handle 23b is disposed above the support member 21. That is to say, the structure for realizing gripping is disposed on the side of the support member 21 facing away from the cover body 1, making the operation more convenient; the support member 21 is clamped between the turntable 23a and the handle 23b, enabling both the turntable 23a and the handle 23b to be directly connected to the support member 21, and increasing the stability of the turntable 23a and the handle 23b.

[0080] Further, a support post 232 is provided on one side of the guide post 231. The support post 232 and the guide post 231 are distributed at intervals around the circumference of the turntable 23a. The guide post 231 and the support post 232 jointly support the lower surface of the support member 21, thereby increasing the stability of the support member 21 and preventing the support member 21 from collapsing or deforming downward.

[0081] Further, a first connection post 233 protrudes upward from the center of the turntable 23a, and a first connection hole 234 is provided at the center of the handle 23b. The first connection post 233 and the first connection hole 234 are in plug-in fit; in the area where the first connection post 233 and the first connection hole 234 are engaged, the cross-section of the first connection post 233 and the cross-section of the first connection hole 234 are set to a non-circular structure. For example, the cross-section of the first connection post 233 and the cross-section of the first connection hole 234 can be set to a triangular shape, a square shape, an oval shape, a polygonal shape, or an irregular shape, etc., thereby preventing the handle 23b and the turntable 23a from relatively rotating and ensuring that the turntable 23a rotates together with the handle 23b.

[0082] Further, a second connection post 235 protrudes downward from the handle 23b, and the second connection post 235 is offset from the center of the handle 23b; the turntable 23a is provided with a second connection hole 236, and the second connection hole 236 is offset from the center of the turntable 23a. The second connection post 235 and the second connection hole 236 are in plug-in fit, which can not only prevent the handle 23b and the turntable 23a from relatively rotating, but also provide a large torque, thereby making the rotation of the turntable 23a easier. Among them, the support member 21 can be provided with an arc-shaped hole 213, and the second connection post 235 passes through the arc-shaped hole 213 and is inserted into the second connection hole 236, forming a limit and a guide for the second connection post 235 through the arc-shaped hole 213 and increasing the stability of the movement of the second connection post 235.

[0083] Further, a plurality of fins 235a protrude from the outer side of the second connecting column 235. The fins 235a extend downward from the handle 23b, and the lower ends of the fins 235a abut against the turntable 23a. The fins 235a are circumferentially spaced around the second connecting column 235 to increase the support strength of the second connecting column 235 and prevent damage such as bending of the second connecting column 235.

[0084] Further, the rotating member 23 further includes a support sleeve 23c and a fastening assembly 23d. The support sleeve 23c is made of a material that is not easily deformed, such as metal. The support sleeve 23c is inserted through the turntable 23a and the handle 23b, thereby playing a role in supporting and strengthening the turntable 23a and the handle 23b. The fastening assembly 23d is inserted through the support sleeve 23c. The fastening assembly 23d axially presses both ends of the support sleeve 23c, and the fastening assembly 23d axially presses the turntable 23a and the handle 23b. By the support sleeve 23c, the axial forces received by the turntable 23a and the handle 23b are restricted, preventing the turntable 23a and the handle 23b from being damaged due to excessive force. Moreover, since the support sleeve 23c is not easily deformed, the axial force of the fastening assembly 23d will not change significantly, thereby preventing loosening of the fastening assembly 23d during use.

[0085] Specifically, the fastening assembly 23d includes a bolt and a nut that cooperate with each other. The bolt has a nut and a screw. The screw is inserted through the support sleeve 23c, and the nut and the nut respectively press both ends of the support sleeve 23c. The radial dimensions of the nut and the nut can be larger than the radial dimension of the support sleeve 23c, so that the edges of the nut and the nut can press the turntable 23a and the handle 23b. Between the nut and the support sleeve 23c, and between the nut and the support sleeve 23c, gaskets can be added. The radial dimension of the gasket is larger than the radial dimensions of the nut and the nut, further increasing the force-bearing area and further achieving an anti-loosening effect.

[0086] As Figures 5-9 shown, further, the rotating member 23 has a first rotation stroke and a second rotation stroke. The first rotation stroke is the use stroke, and the second rotation stroke is the disassembly stroke. Along the direction away from the clamp 22, the guide groove 221 includes a first end point 2211, a separation point 2212, and a second end point 2213. During the first rotation stroke (see Figure 7 and Figure 8 ), the guide post 231 is located between the second end point 2213 and the separation point 2212, and the clamp 22 can be clamped or unclamped. That is to say, in the section where the clamp 22 is close to the axis of the cover body 1, damage to the clamp 22 caused by external forces is prevented, ensuring the safe use of the clamp 22. During the second rotation stroke (see Figure 8 and Figure 9), the guide column 231 is located between the first end point 2211 and the separation point 2212, and the clamp device 2 can be installed and disassembled. That is to say, the clamp 22 is in a section away from the axis of the cover body 1, avoiding interference or collision between the clamp 22 and the edge of the cover body 1 during the disassembly process, thereby ensuring the smooth installation and disassembly of the clamp 22.

[0087] Specifically, a clamping groove is provided on the edge of the clamp 22, and the clamping groove extends along the circumference of the cover body 1, and the opening direction of the clamping groove is toward the axis of the cover body 1; within the first rotation stroke, at least a portion of the edge of the cover body 1 extends into the clamping groove, thereby limiting the relative position of the clamp 22 and the cover body 1 along the axial direction, that is, even if the clamp 22 is impacted by external force, it cannot be separated from the cover body 1, thereby avoiding damage to the connection structure between the clamp device 2 and the cover body 1; within the second rotation stroke, the edge of the cover body 1 can be separated from the clamping groove, so that the clamp device 2 can be smoothly installed and disassembled.

[0088] Furthermore, the check valve 11 is detachably connected to the cover body 1, the clamp 22 is provided with a first avoidance groove 222, the extension direction of the first avoidance groove 222 is parallel to the movement direction of the clamp 22, the check valve 11 is penetrated by the first avoidance groove 222, and can slide along the first avoidance groove 222; when the guide column 231 moves to the separation point 2212 (see Figure 8 ), the check valve 11 and the groove wall of the first avoidance groove 222 abut against each other. Under normal use, the check valve 11 limits the farthest position of the clamp 22. After the clamp 22 slides to the position where the clamp is unclamped, it cannot slide further in the direction away from the axis of the cover body 1, thereby ensuring that the clamp device 2 will not accidentally fall off when in use; when the clamp device 2 needs to be disassembled, the check valve 11 needs to be removed first. After the clamp 22 slides to the position where the clamp is unclamped, it can slide further in the direction away from the axis of the cover body 1 (see Figure 9 ), thereby achieving smooth disassembly of the clamping device 2.

[0089] Furthermore, the first avoidance groove 222 includes a first groove section 222a and a second groove section 222b that are interconnected. The first groove section 222a is farther away from the axis of the cover body 1 than the second groove section 222b. The groove width of the first groove section 222a is greater than the groove width of the second groove section 222b. The check valve 11 can only rise freely in the first groove section 222a, and the check valve 11 cannot rise in the second groove section 222b. When the check valve 11 is in the rising position (see Figure 7 ), the clamp 22 is in the clamping position, the pot is in a high pressure state, the check valve 11 is inserted into the first groove section 222a, and the check valve 11 is stopped in the first groove section 222a and cannot slide into the second groove section 222b, ensuring that it is reliably kept in the clamping position under high pressure, preventing the pot cover from accidentally opening under high pressure; when the check valve 11 is in the lowered position (see Figure 8) The pressure inside the pot is in a low-pressure state. The stop valve 11 can slide into the second groove section 222b along the first groove section 222a, so that the clamp 22 can freely switch between the clamping position and the unclamping position. Moreover, when the clamp 22 moves to the unclamping position, the stop valve 11 stops at one end of the second groove section 222b away from the first groove section 222a, preventing the clamp 22 from further sliding outwards and falling off.

[0090] Furthermore, a first valve sleeve 14 is penetrated through the cover body 1. The first valve sleeve 14 is in sealing fit with the cover body 1 (for example, a sealing ring can be provided), and the first valve sleeve 14 presses the cover body 1 from bottom to top; a second valve sleeve 212 is penetrated through the support member 21, and the second valve sleeve 212 presses the support member 21 from top to bottom; the first valve sleeve 14 is threadedly connected to the second valve sleeve 212, and an installation hole is formed between the first valve sleeve 14 and the second valve sleeve 212; the stop valve 11 is penetrated through the installation hole and can slide along the axis of the installation hole. Adding the mutually cooperating first valve sleeve 14 and second valve sleeve 212 at the installation position of the stop valve 11 functions as a threaded fastener to realize the connection between the support member 21 and the cover body 1, reducing the number of fasteners, lowering the production cost, and eliminating the need to provide dedicated connection holes in the cover body 1 or the support member 21, enabling the pressure cooker lid 01 to maintain a high integrity.

[0091] Furthermore, the pressure cooker lid 01 further includes a first screw 3. The first screw 3 and the stop valve 11 are spaced apart along the movement direction of the clamp 22, and the first screw 3 and the stop valve 11 are respectively located on both sides of the axis of the cover body 1. The first screw 3 passes through the cover body 1 and is connected to the support member 21. The first screw 3 and the valve body together realize the installation and fixation of the support member 21. A relatively large connection span is formed between the first screw 3 and the valve body, thereby increasing the connection reliability and preventing the support member 21 from shaking or rotating, resulting in loosening or falling off of the support member 21.

[0092] Further, the first screw 3 passes through the clamp 22. The clamp 22 is provided with a second avoidance groove 223. The extending direction of the second avoidance groove 223 is parallel to the moving direction of the clamp 22. The first screw 3 is disposed in the second avoidance groove 223 and can slide along the second avoidance groove 223. When the guide post 231 moves to the separation point 2212, the first screw 3 abuts against the groove wall of the second avoidance groove 223. Under normal use conditions, the screw limits the farthest position of the clamp 22. After the clamp 22 slides to the position where the clamping is cancelled, it cannot further slide in the direction away from the axis of the cover body 1, so as to ensure that the clamp device 2 does not accidentally fall off during use. When it is necessary to disassemble the clamp device 2, the screw needs to be removed first. After the clamp 22 slides to the position where the clamping is cancelled, it can further slide in the direction away from the axis of the cover body 1, so as to realize the smooth disassembly of the clamp device 2. It can be understood that the first screw 3 may not pass through the clamp 2. For example, the first screw 3 is disposed on one side of the clamp 22 in the circumferential direction, or the first screw 3 is only fixed to the second part 21b of the support member 21.

[0093] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
